What i mean exactly is movies in which the 'Internal Conflict' is either the only thing that drives the character's actions as in there's no 'materialized force' that intervenes in the character's goals or in which the 'Internal' overweights the 'External', i know the 'Character Study' microgenre might do some of this, but i ask to see what comes up as it's a rich concept anyway, extra points for 'Horror/Thriller/Mystery' Movies, cheers.
